I've always figured it was just good policy to have some basic skill sets like being able to grow a decent amount of food on a small plot of land, do basic and advanced first aid, brew beer, distill liquor, reload ammunition, cook safely and well for large groups of people, etc, etc.
Once one runs out of 'stuff' to trade, skills like some of the above will be worth more than gold.

I bought the entire series off itunes. It’s the first I’ve found that my artsy wife will watch that I think helps inculcate the proper mind-set for living in such situations.
Even the dopey stuff, like the shootout where Hawkins was counting rounds to know when the Ravenwood guy would reload, is useful. It gave me the chance to explain “tactical reload” to her.
I don’t intend any kind of condescention when I say this, but watching Jericho with her is a lot like supervised viewing of “adult” programing with your children. Her mind just doesn’t naturally go in those directions, but I believe it is important to expose her to it to the extent she’ll tolerate.
